2. Description of Related Art
In current information age, it is common that people communicate with each other by electronic communication apparatuses, especially the portable communication apparatuses, such as mobile telephone and other electronic apparatuses with the function of wireless communication. Nowadays, along with the rapid development of the mobile communication technology, the functions of the mobile telephone are continuously developed, including music playing, radio, Personal Digital Assistant (PDA), built-in digital camera, etc.
It should be noted that the foldable cellular phone garners a fairly high market share in the cellular phone market for its multiple operating interfaces and display window of big size. However, with various functions, users of foldable cellular phone needs to input a command to the system of the cellular phone by means of touch input interface for switching to one mode corresponding as required.
Accordingly, the present invention is directed to provide a multi-mode foldable electronic apparatus and the method thereof, for enabling users to switch the multi-mode electronic apparatus among different modes more easily.
The invention provides a multi-mode foldable electronic apparatus and the method thereof based on the above and other purposes of the invention. The multi-mode foldable electronic apparatus comprises a first housing, a second housing, a first hinge, a second hinge, a first magnet, a first magnetism sensor, a second magnet and a second magnetism sensor. The first magnet is disposed in the first housing, and the second magnet is disposed in the first housing and is disposed on one side of the first hinge, in order to rotate along with the first hinge and move along with the first housing being moved. The first magnetism sensor is disposed in the second housing to opposite to the first magnet, for sensing the changes in magnetism of the first magnet as the first magnet being moved. The second magnetism sensor is also disposed in the second housing to opposite to the second magnet, for sensing the changes in magnetism of the second magnet as the second magnet is moved.
According to an embodiment, the first magnetism sensor and the second magnetism sensor are connected to a system.
According to an embodiment of the invention, the first magnetism sensor senses the changes in magnetism of the first magnet, generates a first signal thereby and sends it to the system. The second magnetism sensor senses the changes in magnetism of the second magnet to generate a second signal thereby for sending to the system. When the first housing rotates relative to the second housing via the second hinge, the first magnetism sensor identifies the changes in magnetism of the first magnet as the first magnet being moved to generate a first signal thereby for sending to the system. In the meantime, the second magnetism sensor identifies the changes in magnetism of the second magnet as the second magnet being moved to generate a second signal thereby for sending to the system. The system commends the multi-mode foldable electronic apparatus in a first mode when receiving the first signal and the second signal simultaneously, wherein the first mode may be a Personal Digital Assistant (PDA) mode.
When the first housing rotates relative to the second housing via the first hinge, the first magnetism sensor identifies changes in magnetism of the first magnet as the first magnet being moved to generate a first signal thereby for sending to the system. At this time, the second magnetism sensor does not generate a second signal because it does not identify the changes in magnetism of the second magnet. The system commands the multi-mode foldable electronic apparatus in a second mode when receiving the first signal, wherein the second mode may be a cellular phone mode.
According to an embodiment of the invention, the system commands the multi-mode foldable electronic apparatus in a standby mode when not receiving the first and the second signals.
According to an embodiment of the invention, the first magnetism sensor may be a magneto-resistive sensor, while the second magnetism sensor may be a magneto-resistive sensor.

According to an embodiment of the invention, the multi-mode foldable electronic apparatus can further comprise a touch input interface disposed in the first housing or the second housing.
In order to the make the aforementioned and other objects, features and advantages of the present invention comprehensible, a preferred embodiment accompanied with figures is described in detail below.
It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed.
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
The multi-mode foldable electronic apparatus 100 of the embodiment further comprises a first magnet 150, a first magnetism sensor 160, a second magnet 170 and a second magnetism sensor 180. The first magnet 150 is disposed in the first housing 110 while the circular second magnet 170 is disposed in the first housing 110 and on one side of the hinge 130 to rotate along with the hinge 130 and to move along with the first housing 110. Furthermore, the first magnetism sensor 160 is disposed in the second housing 120 to opposite to the first magnet 150, for sensing changes in magnetism of the first magnet 150 being moved. The second magnetism sensor 180 is also disposed in the second housing 120 to opposite to the second magnet 170, for sensing changes in magnetism of the second magnet 170 being moved. The first magnetism sensor 160 and the second magnetism sensor 180 are connected to a system (not shown), which will command the multi-mode foldable electronic apparatus 100 to switch to different modes corresponding to the signals received. The second magnet 170 disposed on one side of the hinge 130 may not rotate along with the hinge 130 as required in different products.
In the embodiment of the invention, the first magnetism sensor 160 can be a magneto-resistive sensor (MR sensor) or a magnetic pole sensor, while the second magnetism sensor 180 can be a magneto-resistive sensor. Additionally, the multi-mode foldable electronic apparatus 100 may further comprise an image display interface disposed in the first housing 110 for displaying an image. Moreover, the multi-mode foldable electronic apparatus 100 may further comprise a touch input interface (such as a keyboard) disposed in the second housing 120 for enabling the users to input command or data by touch input. To meet the requirements of different product designs, the image display interface can be disposed in the second housing 120 of the multi-mode foldable electronic apparatus 100 and the touch input interface can be disposed in the first housing 110 of the multi-mode foldable electronic apparatus 100 corresponding to the position of the image display interface, without limiting the scope of the invention.

Since the accuracy of sensing signals of a magneto-resistive sensor is higher than that of a magnetic pole sensor. Therefore, when the embodiment uses a magneto-resistive sensor as the second magnetism sensor, inaccuracy in identifying the mode state can be avoided effectively.
Even though the multi-mode foldable electronic apparatus 100 of the embodiment switches among a stand-by mode, a PDA mode and a cellular telephone mode, the design of the multi-mode foldable electronic apparatus 100 can switch to other modes as required. Additionally, the multi-mode foldable electronic apparatus 100 needs to switch to the initial mode, such as: the stand-by mode in
Referring to
When the first housing rotates relative to the second housing via the second hinge, the first magnetism sensor identifies changes in magnetism of the first magnet installed on the first housing as the first magnet being moved to generate a first signal thereby. In the meantime, the second magnetism sensor identifies changes in magnetism of the second magnet installed on the first housing as the second magnet being moved to generate a second signal thereby (see Block 320). In the follow step, the system commands the multi-mode electronic apparatus in a first mode when receiving the first signal and the second signal simultaneously (see Block 325), wherein the first mode is a PDA mode. When the first housing rotates relative to the second housing via the first hinge, the first magnetism sensor identifies changes in magnetism of the first magnet installed on the first housing as the first magnet being moved to generate a first signal thereby (see Block 330). In this case, the system commands the multi-mode foldable electronic apparatus in a second mode when receiving the first signal (see Block 335), wherein the second mode can be a cellular phone mode.
